This file is free documentation; the Free Software Foundation gives unlimited permission to copy, distribute and modify it. Basic Installation ================== Briefly, the shell commands `./configure; make; make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the `README' file for instructions specific to this package. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. Running `configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 6. Often, you can also type `make uninstall' to remove the installed files again. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. With a non-GNU `make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' installs the package's commands under `/usr/local/bin', include files under `/usr/local/include', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option `--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for `CONFIG_SHELL' due to an Autoconf bug. Until the bug is fixed you can use this workaround: CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of the options to `configure', and exit. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. opensmtpd-5.4.2p1/LICENSE010064400017500000000000000407171230532062500142010ustar00gilleswheelThis file is part of the OpenSMTPD software.

It allows ordinary machines to exchange e-mails with other systems speaking the SMTP protocol. OpenSMTPD runs on top of the OpenBSD operating system but also has a portable version that can build and run on several systems, including: * Linux * FreeBSD * NetBSD * DragonFly * MacOSX For more information: [http://www.opensmtpd.org/portable.html](http://www.opensmtpd.org/portable.html) People interested about OpenSMTPD are encouraged to subscribe to our mailing list: [http://www.opensmtpd.org/list.html](http://www.opensmtpd.org/list.html) and to join the IRC channel: #OpenSMTPD @ irc.freenode.net Cheers ! How to build, configure and use Portable OpenSMTPD ================================================== Dependencies ------------ Portable OpenSMTPD relies on: * [autoconf](http://www.gnu.org/software/autoconf/) * [automake](http://www.gnu.org/software/automake/) * [Berkeley DB](http://www.oracle.com/technetwork/products/berkeleydb/overview/index.html) to be built with --enable-compat185 configure flag * [bison](http://www.gnu.org/software/bison/) (or [byacc](http://invisible-island.net/byacc/byacc.html)) * [libevent](http://libevent.org/) * [libtool](http://www.gnu.org/software/libtool/) * [openssl](http://www.openssl.org/) Get the source -------------- git clone -b portable git://github.com/poolpOrg/OpenSMTPD.git opensmtpd or wget http://www.opensmtpd.org/archives/opensmtpd-portable-latest.tar.gz tar xzvf opensmtpd-portable-latest.tar.gz Build ----- cd opensmtpd* ./bootstrap # Only if you build from git sources ./configure make sudo make install ### Special notes for FreeBSD/DragonFlyBSD/Mac OS X: Please launch configure with special directive about libevent directory: #### FreeBSD: ./configure --with-libevent-dir=/usr/local #### DragonFlyBSD: ./configure --with-libevent-dir=/usr/pkg #### Mac OS X: ./configure --with-libevent-dir=/opt/local make CFLAGS="-DBIND_8_COMPAT=1" Install ------- sudo make install Configure /etc/smtpd.conf ------------------------- Please have a look at the complete format description of [smtpd.conf configuration file](http://opensmtpd.org/smtpd.conf.5.html) Add OpenSMTPD users ------------------- To operate, OpenSMTPD requires at least one user, by default _smtpd; and preferably two users, by default _smtpd and _smtpq. Using two users instead of one will increase security by a large factor so... unless you want to voluntarily reduce security or you have absolute more faith in our code than we do, by all means use two. The instructions below assume the default users however, the configure script allows overriding these using the options: --with-privsep-user, --with-queue-user. ### NetBSD, Linux (Debian, ArchLinux, ...) mkdir /var/empty useradd -c "SMTP Daemon" -d /var/empty -s /sbin/nologin _smtpd useradd -c "SMTP queue user" -d /var/empty -s /sbin/nologin _smtpq ### DragonFlyBSD, FreeBSD pw useradd _smtpd -c "SMTP Daemon" -d /var/empty -s /sbin/nologin pw useradd _smtpq -c "SMTP queue user" -d /var/empty -s /sbin/nologin ### Mac OS X First we need a group with an unused GID below 500, list the current ones used: /usr/bin/dscl . -list /Groups PrimaryGroupID | sort -n -k2,2 Add a group - here we have picked 444: /usr/bin/sudo /usr/bin/dscl . -create /Groups/_smtpd PrimaryGroupID 444 Then the user.

The .Ar user must be a valid user name. .Pp The options are as follows: .Bl -tag -width Ds .It Fl f Ar from Specify the sender's name. .It Fl L Don't create a .Pa username.lock file while locking the spool. .It Fl l For compatibility, request that files named .Pa username.lock be used for locking. (This is the default behavior.) .El .Pp Individual mail messages in the mailbox are delimited by an empty line followed by a line beginning with the string .Dq "From\&\ " . A line containing the string .Dq "From\&\ " , the sender's name and a timestamp is prepended to each delivered mail message. A blank line is appended to each message. A greater-than character .Pq Ql > is prepended to any line in the message which could be mistaken for a .Dq "From\&\ " delimiter line. .Pp Significant efforts have been made to ensure that .Nm acts as securely as possible if the spool directory is mode 1777 or 755. The default of mode 755 is more secure, but it prevents mail clients from using .Pa username.lock style locking. The use of 1777 is more flexible in an NFS shared-spool environment, so many sites use it. However, it does carry some risks, such as attackers filling the spool disk. Some of these problems may be alleviated by making the spool a separate filesystem, and placing quotas on it. The use of any mode other than 1777 and 755 for the spool directory is recommended against but may work properly. .Pp The mailbox is always locked using .Xr flock 2 while mail is appended. Unless the .Fl L flag is specified, a .Pa username.lock file is also used. .Pp If the .Xr biff 1 service is returned by .Xr getservbyname 3 , the biff server is notified of delivered mail. .Sh ENVIRONMENT .Bl -tag -width indent .It Ev TZ Used to set the appropriate time zone on the timestamp. .El .Sh FILES .Bl -tag -width /tmp/local.XXXXXXXXXX -compact .It Pa /tmp/local.XXXXXXXXXX temporary files .It Pa /var/mail/user user's mailbox directory .El .Sh EXIT STATUS .Ex -std mail.local .Sh SEE ALSO .Xr biff 1 , .Xr mail 1 , .Xr flock 2 , .Xr getservbyname 3 , .Xr comsat 8 , .Xr sendmail 8 .Sh HISTORY A superset of .Nm (handling mailbox reading as well as mail delivery) appeared in .At v7 as the program .Xr mail 1 . .Sh BUGS Since .Xr sendmail 8 bases its idea of whether a message has been delivered or not on the return value from .Nm mail.local , using quotas in .Pa /var/mail can be problematic. By default, .Xr sendmail 8 will ask .Nm to deliver a message to multiple recipients if possible. This causes problems in a quota environment since a message may be delivered to some users but not others due to disk quotas. Even though the message was delivered to some of the recipients, .Nm will exit with an exit code > 0, causing .Xr sendmail 8 to attempt redelivery later. That means that some users will keep getting the same message every time .Xr sendmail 8 runs its queue. .Pp If you are running with disk quotas on .Pa /var/mail it is imperative that you unset the .Dq m mailer flag for the .Sq local mailer. To do this, locate the line beginning with .Dq Mlocal in .Pa /etc/mail/sendmail.cf and remove the .Dq m from the flags section, denoted by .Dq F= . Alternately, you can override the default mailer flags by adding the line: .Pp .Dl define(`LOCAL_MAILER_FLAGS', `rn9S')dnl .Pp to your .Dq \.mc file (this is the source file that is used to generate .Pa /etc/mail/sendmail.cf ) . opensmtpd-5.4.2p1/contrib/libexec/mail.local/mail.local.c010064400017500000000000000210551230532062500224330ustar00gilleswheel/* $OpenBSD: mail.local.c,v 1.32 2009/10/27 23:59:31 deraadt Exp $ */ /*- * Copyright (c) 1996-1998 Theo de Raadt * Copyright (c) 1996-1998 David Mazieres * Copyright (c) 1990 The Regents of the University of California. * All rights reserved. * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * 1.

It is reproduced here in a slightly edited form for convenience. A 65-character subset of US-ASCII is used, enabling 6 bits to be represented per printable character. (The extra 65th character, "=", is used to signify a special processing function.) The encoding process represents 24-bit groups of input bits as output strings of 4 encoded characters. Proceeding from left to right, a 24-bit input group is formed by concatenating 3 8-bit input groups. These 24 bits are then treated as 4 concatenated 6-bit groups, each of which is translated into a single digit in the base64 alphabet. Each 6-bit group is used as an index into an array of 64 printable characters. The character referenced by the index is placed in the output string. Table 1: The Base64 Alphabet Value Encoding Value Encoding Value Encoding Value Encoding 0 A 17 R 34 i 51 z 1 B 18 S 35 j 52 0 2 C 19 T 36 k 53 1 3 D 20 U 37 l 54 2 4 E 21 V 38 m 55 3 5 F 22 W 39 n 56 4 6 G 23 X 40 o 57 5 7 H 24 Y 41 p 58 6 8 I 25 Z 42 q 59 7 9 J 26 a 43 r 60 8 10 K 27 b 44 s 61 9 11 L 28 c 45 t 62 + 12 M 29 d 46 u 63 / 13 N 30 e 47 v 14 O 31 f 48 w (pad) = 15 P 32 g 49 x 16 Q 33 h 50 y Special processing is performed if fewer than 24 bits are available at the end of the data being encoded. A full encoding quantum is always completed at the end of a quantity. When fewer than 24 input bits are available in an input group, zero bits are added (on the right) to form an integral number of 6-bit groups. Padding at the end of the data is performed using the '=' character. Since all base64 input is an integral number of octets, only the ------------------------------------------------- following cases can arise: (1) the final quantum of encoding input is an integral multiple of 24 bits; here, the final unit of encoded output will be an integral multiple of 4 characters with no "=" padding, (2) the final quantum of encoding input is exactly 8 bits; here, the final unit of encoded output will be two characters followed by two "=" padding characters, or (3) the final quantum of encoding input is exactly 16 bits; here, the final unit of encoded output will be three characters followed by one "=" padding character. */ #if !defined(HAVE_B64_NTOP) && !defined(HAVE___B64_NTOP) int b64_ntop(u_char const *src, size_t srclength, char *target, size_t targsize) { size_t datalength = 0; u_char input[3]; u_char output[4]; u_int i; while (2 < srclength) { input[0] = *src++; input[1] = *src++; input[2] = *src++; srclength -= 3; output[0] = input[0] >> 2; output[1] = ((input[0] & 0x03) << 4) + (input[1] >> 4); output[2] = ((input[1] & 0x0f) << 2) + (input[2] >> 6); output[3] = input[2] & 0x3f; if (datalength + 4 > targsize) return (-1); target[datalength++] = Base64[output[0]]; target[datalength++] = Base64[output[1]]; target[datalength++] = Base64[output[2]]; target[datalength++] = Base64[output[3]]; } /* Now we worry about padding. */ if (0 != srclength) { /* Get what's left. */ input[0] = input[1] = input[2] = '\0'; for (i = 0; i < srclength; i++) input[i] = *src++; output[0] = input[0] >> 2; output[1] = ((input[0] & 0x03) << 4) + (input[1] >> 4); output[2] = ((input[1] & 0x0f) << 2) + (input[2] >> 6); if (datalength + 4 > targsize) return (-1); target[datalength++] = Base64[output[0]]; target[datalength++] = Base64[output[1]]; if (srclength == 1) target[datalength++] = Pad64; else target[datalength++] = Base64[output[2]]; target[datalength++] = Pad64; } if (datalength >= targsize) return (-1); target[datalength] = '\0'; /* Returned value doesn't count \0. */ return (datalength); } #endif /* !defined(HAVE_B64_NTOP) && !defined(HAVE___B64_NTOP) */ #if !defined(HAVE_B64_PTON) && !defined(HAVE___B64_PTON) /* skips all whitespace anywhere. converts characters, four at a time, starting at (or after) src from base - 64 numbers into three 8 bit bytes in the target area. it returns the number of data bytes stored at the target, or -1 on error. */ int b64_pton(char const *src, u_char *target, size_t targsize) { u_int tarindex, state; int ch; char *pos; state = 0; tarindex = 0; while ((ch = *src++) != '\0') { if (isspace(ch)) /* Skip whitespace anywhere. */ continue; if (ch == Pad64) break; pos = strchr(Base64, ch); if (pos == 0) /* A non-base64 character. */ return (-1); switch (state) { case 0: if (target) { if (tarindex >= targsize) return (-1); target[tarindex] = (pos - Base64) << 2; } state = 1; break; case 1: if (target) { if (tarindex + 1 >= targsize) return (-1); target[tarindex] |= (pos - Base64) >> 4; target[tarindex+1] = ((pos - Base64) & 0x0f) << 4 ; } tarindex++; state = 2; break; case 2: if (target) { if (tarindex + 1 >= targsize) return (-1); target[tarindex] |= (pos - Base64) >> 2; target[tarindex+1] = ((pos - Base64) & 0x03) << 6; } tarindex++; state = 3; break; case 3: if (target) { if (tarindex >= targsize) return (-1); target[tarindex] |= (pos - Base64); } tarindex++; state = 0; break; } } /* * We are done decoding Base-64 chars.

The elements * are singly linked for minimum space and pointer manipulation overhead at * the expense of O(n) removal for arbitrary elements. New elements can be * added to the list after an existing element or at the head of the list. * Elements being removed from the head of the list should use the explicit * macro for this purpose for optimum efficiency. A singly-linked list may * only be traversed in the forward direction. Singly-linked lists are ideal * for applications with large datasets and few or no removals or for * implementing a LIFO queue. * * A list is headed by a single forward pointer (or an array of forward * pointers for a hash table header). The elements are doubly linked * so that an arbitrary element can be removed without a need to * traverse the list. New elements can be added to the list before * or after an existing element or at the head of the list. A list * may only be traversed in the forward direction. * * A simple queue is headed by a pair of pointers, one the head of the * list and the other to the tail of the list. The elements are singly * linked to save space, so elements can only be removed from the * head of the list. New elements can be added to the list before or after * an existing element, at the head of the list, or at the end of the * list. A simple queue may only be traversed in the forward direction. * * A tail queue is headed by a pair of pointers, one to the head of the * list and the other to the tail of the list. The elements are doubly * linked so that an arbitrary element can be removed without a need to * traverse the list. New elements can be added to the list before or * after an existing element, at the head of the list, or at the end of * the list. A tail queue may be traversed in either direction. * * A circle queue is headed by a pair of pointers, one to the head of the * list and the other to the tail of the list. The elements are doubly * linked so that an arbitrary element can be removed without a need to * traverse the list. New elements can be added to the list before or after * an existing element, at the head of the list, or at the end of the list. * A circle queue may be traversed in either direction, but has a more * complex end of list detection. * * For details on the use of these macros, see the queue(3) manual page. */ #if defined(QUEUE_MACRO_DEBUG) || (defined(_KERNEL) && defined(DIAGNOSTIC)) #define _Q_INVALIDATE(a) (a) = ((void *)-1) #else #define _Q_INVALIDATE(a) #endif /* * Singly-linked List definitions. */ #define SLIST_HEAD(name, type) \ struct name { \ struct type *slh_first;

An alias in its simplest form is used to assign an arbitrary name to an email address, or a group of email addresses. This provides a convenient way to send mail. For example an alias could refer to all users of a group: email to that alias would be sent to all members of the group. Much more complex aliases can be defined however: an alias can refer to other aliases, be used to send mail to a file instead of another person, or to execute various commands. .Pp Within the file, .Ql # is a comment delimiter; anything placed after it is discarded. The file consists of key/value mappings of the form: .Bd -filled -offset indent key: value1, value2, value3, ... .Ed .Pp .Em key is always folded to lowercase before alias lookups to ensure that there can be no ambiguity. The key is expanded to the corresponding values, which consist of one or more of the following: .Bl -tag -width Ds .It Em user A user on the host machine. The user must have a valid entry in the .Xr passwd 5 database file. .It Ar /path/to/file Append messages to .Ar file , specified by its absolute pathname. .It | Ns Ar command Pipe the message to .Ar command on its standard input. The command is run under the privileges of the daemon's unprivileged account. .It No : Ns Ar include : Ns Ar /path/to/file Include any definitions in .Ar file as alias entries. The format of the file is identical to this one. .It Ar user-part@domain-part An email address in RFC 5322 format (see .Xr mailaddr 7 ) . If an address extension is appended to the user-part, it is stripped so that an address such as user+ext@example.com will only use the part that precedes .Sq + as a .Em key . .It Ar error : Ns Ar code Ar message A status code and message to return. The code must be 3 digits, starting 4XX (TempFail) or 5XX (PermFail). The message must be present and can be freely chosen. .El .Sh FILES .Bl -tag -width "/etc/mail/aliasesXXX" .It Pa /etc/mail/aliases Default .Nm file. .El .Sh SEE ALSO .Xr smtpd.conf 5 , .Xr makemap 8 , .Xr newaliases 8 , .Xr smtpd 8 .Sh HISTORY The .Nm file format appeared in .Bx 4.0 . opensmtpd-5.4.2p1/smtpd/aliases.c010064400017500000000000000120541230532062500161010ustar00gilleswheel/* $OpenBSD$ */ /* * Copyright (c) 2008 Gilles Chehade * * Permission to use, copy, modify, and distribute this software for any * purpose with or without fee is hereby granted, provided that the above * copyright notice and this permission notice appear in all copies. * * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF * MERCHANTABILITY AND FITNESS.

If this file exists, .Xr smtpd 8 forwards email to the destinations specified therein. .Pp A .Nm .forward file contains a list of expansion values, as described in .Xr aliases 5 . Each expansion value should be on a line by itself. However, the .Nm .forward mechanism differs from the aliases mechanism in that is disallows file inclusion .Pq :include: and it performs expansion under the user ID of the .Nm .forward file owner. .Pp Permissions on the .Nm .forward file are very strict and expansion is rejected if the file is group or world-writable; if the home directory is group writeable; or if the file is not owned by the user. .Pp Users should avoid editing directly the .Nm .forward file to prevent delivery failures from occurring if a message arrives while the file is not fully written. The best option is to use a temporary file and use the .Xr mv 1 command to atomically overwrite the former .Nm .forward . Alternatively, setting the .Xr sticky 8 bit on the home directory will cause the .Nm .forward lookup to return a temporary failure, causing mails to be deferred. .Sh FILES .Bl -tag -width "~/.forwardXXX" -compact .It Pa ~/.forward Email forwarding information. .El .Sh EXAMPLES The following file forwards mail to .Dq user@example.com , and pipes the same mail to .Dq examplemda . .Bd -literal -offset indent # empty lines are ignored user@example.com # anything after # is ignored "|/path/to/examplemda" .Ed .Sh SEE ALSO .Xr aliases 5 , .Xr smtpd 8 opensmtpd-5.4.2p1/smtpd/forward.c010064400017500000000000000045601230532062500161270ustar00gilleswheel/* $OpenBSD$ */ /* * Copyright (c) 2008 Gilles Chehade * * Permission to use, copy, modify, and distribute this software for any * purpose with or without fee is hereby granted, provided that the above * copyright notice and this permission notice appear in all copies. * * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF * MERCHANTABILITY AND FITNESS.

Such associations may be accessed through a plaintext file, database, or DNS. The format of these file types is described below. .Nm itself creates the database maps used by keyed map lookups specified in .Xr smtpd.conf 5 . .Pp .Nm reads input from .Ar file and writes data to a file whose name is made by adding a .Dq .db suffix to .Ar file . In all cases, .Nm reads lines consisting of words separated by whitespace. The first word of a line is the database key; the remainder represents the mapped value. The database key and value may optionally be separated by the colon character. .Pp The options are as follows: .Bl -tag -width Ds .It Fl o Ar dbfile Write the generated database to .Ar dbfile . .It Fl t Ar type Specify the format of the resulting map file. The default map format is suitable for storing simple, unstructured, key-to-value string associations. However, if the mapped value has special meaning, as in the case of the virtual domains file, a suitable .Ar type must be provided. The available output types are: .Bl -tag -width "aliases" .It Cm aliases The mapped value is a comma-separated list of mail destinations. This format can be used for building user aliases and user mappings for virtual domain files. .It Cm set There is no mapped value \(en a map of this type will only allow for the lookup of keys. This format can be used for building primary domain maps. .El .El .Sh PRIMARY DOMAINS Primary domains can be kept in tables. To create a primary domain table, add each primary domain on a single line by itself. .Pp In addition to adding an entry to the primary domain map, one must add a filter rule that accepts mail for the domain map, for example: .Bd -literal -offset indent table domains "/etc/mail/domains" accept for domain deliver to mbox .Ed .Sh VIRTUAL DOMAINS Virtual domains may also be kept in tables. To create a virtual domain table, add each virtual domain on a single line by itself. .Pp Virtual domains expect a mapping of virtual users to real users in order to determine if a recipient is accepted or not. The mapping format is an extension to .Xr aliases 5 , which allows the use of .Dq user@domain.tld to accept user only on the specified domain, .Dq user to accept the user for any of the virtual domains, .Dq @domain.tld to provide a catch-all for the specified domain and .Dq @ to provide a global catch-all for all domains. .Xr smtpd 8 will perform the lookups in that specific order. .Pp To create single virtual address, add .Dq user@example.com user to the users map. To handle all mail destined to any user at example.com, add .Dq @example.com user to the virtual map. .Pp In addition to adding an entry to the virtual map, one must add a filter rule that accepts mail for virtual domains, for example: .Bd -literal -offset indent table vdomains "/etc/mail/vdomains" table vusers "/etc/mail/users" accept for domain virtual deliver to mbox accept for domain example.org virtual deliver to mbox .Ed .Sh FILES .Bl -tag -width "/etc/mail/aliasesXXX" -compact .It Pa /etc/mail/aliases List of user mail aliases. .It Pa /etc/mail/secrets List of remote host credentials. .El .Sh EXIT STATUS .Ex -std makemap .Sh SEE ALSO .Xr aliases 5 , .Xr smtpd.conf 5 , .Xr editmap 8 , .Xr newaliases 8 , .Xr smtpd 8 .Sh HISTORY The .Nm command first appeared in .Ox 4.6 as a replacement for the equivalent command shipped with sendmail. opensmtpd-5.4.2p1/smtpd/makemap.c010064400017500000000000000224361230532062500161000ustar00gilleswheel/* $OpenBSD$ */ /* * Copyright (c) 2008 Gilles Chehade * Copyright (c) 2008-2009 Jacek Masiulaniec * * Permission to use, copy, modify, and distribute this software for any * purpose with or without fee is hereby granted, provided that the above * copyright notice and this permission notice appear in all copies. * * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF * MERCHANTABILITY AND FITNESS.

This utility must be run each time the aliases file is changed in order for the change to take effect. .Pp The options are as follows: .Bl -tag -width Ds .It Fl f Ar file Use .Ar file as the configuration file, instead of the default .Pa /etc/mail/smtpd.conf . .El .Pp Note: this utility is provided for sendmail compatibility. The preferred way of rebuilding the database is with .Xr makemap 8 : .Bd -literal -offset indent # makemap -t aliases /etc/mail/aliases .Ed .Sh FILES .Bl -tag -width "/etc/mail/aliasesXXX" -compact .It Pa /etc/mail/aliases List of local user mail aliases. .It Pa /etc/mail/virtual List of virtual host aliases. .El .Sh EXIT STATUS .Ex -std newaliases .Sh SEE ALSO .Xr smtpd.conf 5 , .Xr makemap 8 .Sh HISTORY The .Nm command first appeared in .Ox 4.6 as a replacement for the equivalent command shipped with sendmail. opensmtpd-5.4.2p1/smtpd/parse.y010064400017500000000000001370071230532062500156260ustar00gilleswheel/* $OpenBSD$ */ /* * Copyright (c) 2008 Gilles Chehade * Copyright (c) 2008 Pierre-Yves Ritschard * Copyright (c) 2002, 2003, 2004 Henning Brauer * Copyright (c) 2001 Markus Friedl.

The message is read on standard input (stdin) until .Nm encounters an end-of-file. The .Nm enqueuer is not intended to be used directly to send mail, but rather via a frontend known as a mail user agent. .Pp Unless the optional .Fl t flag is specified, one or more recipients must be specified on the command line. .Pp The options are as follows: .Bl -tag -width Ds .It Fl F Ar name Set the sender's full name. .It Fl f Ar from Set the sender's address. .It Fl t Read the message's To:, Cc:, and Bcc: fields for recipients. The Bcc: field will be deleted before sending. .It Fl v Enable verbose output. .El .Pp To maintain compatibility with Sendmail, Inc.'s implementation of .Nm , various other flags are accepted, but have no effect. .Sh EXIT STATUS .Ex -std .Sh SEE ALSO .Xr smtpctl 8 , .Xr smtpd 8 .Sh AUTHORS .Sy OpenSMTPD is primarily developed by Gilles Chehade, Eric Faurot, and Charles Longeau, with contributions from various .Ox hackers.

Commands may be abbreviated to the minimum unambiguous prefix; for example, .Cm sh s for .Cm show stats . .Pp The following commands are available: .Bl -tag -width Ds .It Cm encrypt Op Ar string Encrypt the password .Ar string to a representation suitable for user credentials and print it to the standard output. If .Ar string is not provided, cleartext passwords are read from standard input. .Pp It is advised to avoid providing the password as a parameter as it will be visible from .Xr top 1 and .Xr ps 1 output. .It Cm log brief Disable verbose debug logging. .It Cm log verbose Enable verbose debug logging. .It Cm monitor Display updates of some .Xr smtpd 8 internal counters in one second intervals. Each line reports the increment of all counters since the last update, except for some counters which are always absolute values. The first line reports the current value of each counter. The fields are: .Pp .Bl -bullet -compact .It Current number of active SMTP clients (absolute value). .It New SMTP clients. .It Disconnected clients. .It Current number of envelopes in the queue (absolute value). .It Newly enqueued envelopes. .It Dequeued envelopes. .It Successful deliveries. .It Temporary failures. .It Permanent failures. .It Message loops. .It Expired envelopes. .It Envelopes removed by the administrator. .It Generated bounces. .El .It Cm pause envelope Ar envelope-id | message-id Temporarily suspend scheduling for the envelope with the given ID, or all envelopes with the given message ID. .It Cm pause mda Temporarily stop deliveries to local users. .It Cm pause mta Temporarily stop relaying and deliveries to remote users. .It Cm pause smtp Temporarily stop accepting incoming sessions. .It Cm profile Ar subsystem Enables real-time profiling of .Ar subsystem . Supported subsystems are: .Pp .Bl -bullet -compact .It queue, to profile cost of queue IO .It imsg, to profile cost of event handlers .El .It Cm remove Ar envelope-id | message-id Remove a single envelope, or all envelopes with the same message ID. .It Cm resume envelope Ar envelope-id | message-id Resume scheduling for the envelope with the given ID, or all envelopes with the given message ID. .It Cm resume mda Resume deliveries to local users. .It Cm resume mta Resume relaying and deliveries to remote users. .It Cm resume route Ar route-id Resume routing on disabled route .Ar route-id . .It Cm resume smtp Resume accepting incoming sessions. .It Cm schedule all Mark all envelopes as ready for immediate delivery. .It Cm schedule Ar envelope-id | message-id Mark a single envelope, or all envelopes with the same message ID, as ready for immediate delivery. .It Cm show envelope Ar envelope-id Display envelope content for the given ID. .It Cm show hosts Display the list of known remote MX hosts. For each of them, it shows the IP address, the canonical hostname, a reference count, the number of active connections to this host, and the elapsed time since the last connection. .It Cm show hoststats Display status of last delivery for domains that have been active in the last 4 hours. It consists of the following fields, separated by a "|": .Pp .Bl -bullet -compact .It Domain. .It .Ux timestamp of last delivery. .It Status of last delivery. .El .It Cm show message Ar envelope-id Display message content for the given ID. .It Cm show queue Display information concerning envelopes that are currently in the queue. Each line of output describes a single envelope. It consists of the following fields, separated by a "|": .Pp .Bl -bullet -compact .It Envelope ID. .It Address family of the client which enqueued the mail. .It Type of delivery: one of "mta", "mda" or "bounce". .It Various flags on the envelope. .It Sender address (return path). .It The original recipient address. .It The destination address. .It Time of creation. .It Time of expiration. .It Time of last delivery or relaying attempt. .It Number of delivery or relaying attempts. .It Current runstate: either "pending" or "inflight" if .Xr smtpd 8 is running, or "offline" otherwise. .It Delay in seconds before the next attempt if pending, or time ellapsed if currently running. This field is blank if .Xr smtpd 8 is not running. .It Error string for the last failed delivery or relay attempt. .El .It Cm show relays Display the list of currently active relays and associated connectors. For each relay, it shows a number of counters and information on its internal state on a single line. Then comes the list of connectors (source addresses to connect from for this relay). .It Cm show routes Display status of routes currently known by .Xr smtpd 8 . Each line consists of a route number, a source address, a destination address, a set of flags, the number of connections on this route, the current penalty level which determines the amount of time the route is disabled if an error occurs, and the delay before it gets reactivated. The following flags are defined: .Pp .Bl -tag -width xx -compact .It D The route is currently disabled. .It N The route is new. No SMTP session has been established yet. .It Q The route as a timeout registered to lower its penalty level and possibly reactivate or discard it. .El .It Cm show stats Displays runtime statistics concerning .Xr smtpd 8 . .It Cm show status Shows if MTA, MDA and SMTP systems are currently running or paused. .It Cm stop Stop the server. .It Cm trace Ar subsystem Enables real-time tracing of .Ar subsystem . Supported subsystems are: .Pp .Bl -bullet -compact .It imsg .It io .It smtp (incoming sessions) .It filter .It transfer (outgoing sessions) .It bounce .It scheduler .It expand (aliases/virtual/forward expansion) .It lookup (user/credentials lookups) .It stat .It rules (matched by incoming sessions) .It mproc .It all .El .It Cm unprofile Ar subsystem Disables real-time profiling of .Ar subsystem . .It Cm untrace Ar subsystem Disables real-time tracing of .Ar subsystem . .It Cm update table Ar name For table backends that provide caching, causes .Xr smtpd 8 to update the cache. .El .Pp When .Nm smtpd receives a message, it generates a .Ar message-id for the message, and one .Ar envelope-id per recipient. The .Ar message-id is a 32-bit random identifier that is guaranteed to be unique on the host system. The .Ar envelope-id is a 64-bit unique identifier that encodes the .Ar message-id in the 32 upper bits and a random envelope identifier in the 32 lower bits. .Pp A command which specifies a .Ar message-id applies to all recipients of a message; a command which specifies an .Ar envelope-id applies to a specific recipient of a message. .Sh FILES .Bl -tag -width "/var/run/smtpd.sockXX" -compact .It /var/run/smtpd.sock .Ux Ns -domain socket used for communication with .Xr smtpd 8 . .El .Sh SEE ALSO .Xr smtpd 8 .Sh HISTORY The .Nm program first appeared in .Ox 4.6 . opensmtpd-5.4.2p1/smtpd/smtpctl.c010064400017500000000000000637111230532062500161540ustar00gilleswheel/* $OpenBSD$ */ /* * Copyright (c) 2013 Eric Faurot * Copyright (c) 2006 Gilles Chehade * Copyright (c) 2006 Pierre-Yves Ritschard * Copyright (c) 2005 Claudio Jeker * Copyright (c) 2004, 2005 Esben Norby * Copyright (c) 2003 Henning Brauer * * Permission to use, copy, modify, and distribute this software for any * purpose with or without fee is hereby granted, provided that the above * copyright notice and this permission notice appear in all copies. * * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF * MERCHANTABILITY AND FITNESS.

It can relay messages through remote mail transfer agents or store them locally using either the mbox or maildir format. This implementation supports SMTP as defined by RFC 5321 as well as several extensions. A running .Nm can be controlled through .Xr smtpctl 8 . .Pp The options are as follows: .Bl -tag -width Ds .It Fl D Ar macro Ns = Ns Ar value Define .Ar macro to be set to .Ar value on the command line. Overrides the definition of .Ar macro in the configuration file. .It Fl d Do not daemonize. If this option is specified, .Nm will run in the foreground and log to .Em stderr . .It Fl f Ar file Specify an alternative configuration file. .It Fl n Configtest mode. Only check the configuration file for validity. .It Fl P Ar system Pause a specific subsystem at startup. Normal operation can be resumed using .Xr smtpctl 8 . This option can be used multiple times. The accepted values are: .Pp .Bl -tag -width "smtpXXX" -compact .It mda Do not schedule local deliveries. .It mta Do not schedule remote transfers. .It smtp Do not listen on SMTP sockets. .El .It Fl v Produce more verbose output. .El .Pp If you are running a BSD Operating System, you should use and modify .Xr mailwrapper 8 settings by editing .Pa /etc/mailer.conf : .Bd -literal -offset indent sendmail /usr/sbin/smtpctl send-mail /usr/sbin/smtpctl mailq /usr/sbin/smtpctl makemap /usr/libexec/smtpd/makemap newaliases /usr/libexec/smtpd/makemap .Ed .Pp Disable the sendmail clientmqueue entry in .Xr crontab 1 . .Pp Rebuild the aliases database, and enable the daemon: .Bd -literal -offset indent # newaliases # /etc/rc.d/smtpd start .Ed .Sh FILES .Bl -tag -width "/var/run/smtpd.sockXXX" -compact .It Pa /etc/mail/mailname Alternate server name to use. .It Pa /etc/mail/smtpd.conf Default .Nm configuration file. .It Pa /var/run/smtpd.sock .Ux Ns -domain socket used for communication with .Xr smtpctl 8 . .El .Sh SEE ALSO .Xr smtpd.conf 5 , .Xr mailwrapper 8 , .Xr smtpctl 8 .Sh STANDARDS .Rs .%A J. Klensin .%D October 2008 .%R RFC 5321 .%T Simple Mail Transfer Protocol .Re .Sh HISTORY The .Nm program first appeared in .Ox 4.6 . .Sh CAVEATS Because .Xr sendmail 8 is still the de facto .Ox mailer, .Nm versions of .Xr aliases 5 , .Xr forward 5 , .Xr makemap 8 , and .Xr newaliases 8 are not currently installed. opensmtpd-5.4.2p1/smtpd/smtpd.c010064400017500000000000001123701230532062500156110ustar00gilleswheel/* $OpenBSD$ */ /* * Copyright (c) 2008 Gilles Chehade * Copyright (c) 2008 Pierre-Yves Ritschard * Copyright (c) 2009 Jacek Masiulaniec * * Permission to use, copy, modify, and distribute this software for any * purpose with or without fee is hereby granted, provided that the above * copyright notice and this permission notice appear in all copies. * * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF * MERCHANTABILITY AND FITNESS.

Comments can be put anywhere in the file using a hash mark .Pq Sq # , and extend to the end of the current line. Care should be taken when commenting out multi-line text: the comment is effective until the end of the entire block. .Pp Argument names not beginning with a letter, digit, or underscore must be quoted. Arguments containing whitespace should be surrounded by double quotes .Pq \&" . .Pp Macros can be defined that will later be expanded in context. Macro names must start with a letter, digit, or underscore, and may contain any of those characters. Macro names may not be reserved words (for example .Ar listen , .Ar accept , .Ar port ) . Macros are not expanded inside quotes. .Pp For example: .Bd -literal -offset indent lan_addr = "192.168.0.1" listen on $lan_addr listen on $lan_addr tls auth .Ed .Pp Additional configuration files can be included with the .Ic include keyword, for example: .Bd -literal -offset indent include "/etc/mail/smtpd.conf.local" .Ed .Pp The syntax of .Nm is described below. .Bl -tag -width Ds .It Ic accept | reject .Xr smtpd 8 accepts and rejects messages based on information gathered during the SMTP session. .Pp For each message processed by the daemon, the filter rules are evaluated in sequential order, from first to last. The first matching rule decides what action is taken. If no rule matches the message, the default action is to reject the message. An exclamation mark may be specified to perform a reverse match. .Pp Following the accept/reject decision comes the optional tag matching: .Bl -tag -width Ds .It Xo .Ic tagged .Op Ic \&! .Ic tag .Xc If specified, the rule will only be matched if the client session was tagged with .Ar tag . .El .Pp After that the client's IP address filter is specified: .Bl -tag -width Ds .It Ic from any Make the rule match regardless of the IP of connecting client. .It Xo .Ic from .Op Ic \&! .Ic local .Xc The rule matches only locally originating connections. This is the default, and may be omitted. .It Xo .Ic from .Op Ic \&! .Ic source .Ic table .Xc The rule matches if the connection is made from a client whose address is declared in the table .Ar table . .El .Pp In addition, finer filtering may be achieved on the sender if desired: .Bl -tag -width Ds .It Xo .Ic sender .Op Ic \&! .Ic senders .Xc If specified, the rule will only be matched if the sender email address is found in the table .Ar senders . The table may contain complete email addresses or apply to an entire domain if prefixed with @. .El .Pp Next comes the selection based on the domain the message is sent to: .Bl -tag -width Ds .It Ic for any Op Ic alias Aq Ar aliases Make the rule match regardless of the domain it is sent to. If specified, the table .Ar aliases is used for looking up alternative destinations for all addresses. .It Ic for any virtual Aq Ar vmap Make the rule match regardless of the domain it is sent to. The .Ar vmap table will be used as the virtual domain mapping. .It Xo .Ic for .Op Ic \&! .Ic domain .Ar domain .Op Ic alias Aq Ar aliases .Xc This rule applies to mail destined for the specified .Ar domain . This parameter supports the .Sq * wildcard, so that a single rule for all sub-domains can be used, for example: .Bd -literal -offset indent accept for domain "*.example.com" deliver to mbox .Ed .Pp If specified, the table .Ar aliases is used for looking up alternative destinations for addresses in this .Ar domain . .It Xo .Ic for .Op Ic \&! .Ic domain .Aq Ar domains .Op Ic alias Aq Ar aliases .Xc This rule applies to mail destined to domains which are part of the table .Ar domains . .Pp If specified, the table .Ar aliases is used for looking up alternative destinations for addresses in these .Ar domains . .It Xo .Ic for .Op Ic \&! .Ic domain .Ar domain .Ic virtual Aq Ar users .Xc This rule applies to mail destined for the specified virtual .Ar domain . This parameter supports the .Sq * wildcard, so that a single rule for all sub-domains can be used, for example: .Bd -literal -offset indent accept for domain "*.example.com" \e virtual deliver to mbox .Ed .Pp The table .Ar users holds a key-value mapping of virtual to system users. For an example of how to configure the .Ar users table, see .Xr makemap 8 . .It Xo .Ic for .Op Ic \&! .Ic domain .Ao Ar domains .Ac Ic virtual Aq Ar users .Xc This rule applies to mail destined for the virtual domains specified in the table .Ar domains . .Pp The table .Ar users holds a key-value mapping of virtual to system users. For an example of how to configure the .Ar users table, see .Xr makemap 8 . .It Xo .Ic for .Op Ic \&! .Ic local .Op Ic alias Aq Ar aliases .Xc This rule applies to mail destined to .Dq localhost and to the default server name. See the .Sx FILES entry for .Pa /etc/mail/mailname below for details of how the server name is determined. .It Xo .Ic for .Op Ic \&! .Ic local .Ic virtual Aq Ar vmap .Xc This rule applies to mail destined to .Dq localhost and to the default server name. The .Ar vmap table will be used as the virtual domain mapping. .El .Pp Further filtering may be achieved on specific recipients if desired: .Bl -tag -width Ds .It Xo .Ic recipient .Op Ic \&! .Ar recipients .Xc If specified, the rule will only be matched if the recipient email address is found in the table .Ar recipients . The table may contain complete email addresses or apply to an entire domain if prefixed with .Sq @ . .El .Pp If the method of delivery is local, a user database may be specified to override the system database: .Bl -tag -width Ds .It Op Ic userbase Aq Ar table Look up users in the table .Ar table instead of performing system lookups using the .Xr getpwnam 3 function. .El .Pp Finally, the method of delivery is specified: .Bl -tag -width Ds .It Ic deliver to lmtp Op Ar host : Ns Ar port | socket Mail is delivered to .Ar host : Ns Ar port , or to the .Ux .Ar socket over LMTP. .It Ic deliver to maildir Ar path Mail is added to a maildir. Its location, .Ar path , may contain format specifiers that are expanded before use .Pq see Sx FORMAT SPECIFIERS . If .Ar path is not provided, then .Pa ~/Maildir is assumed. .It Ic deliver to mbox Mail is delivered to the local user's system mailbox in .Pa /var/mail . .It Ic deliver to mda Ar program Mail is piped to the specified .Ar program , which is run with the privileges of the user the message is destined to. This parameter may use conversion specifiers that are expanded before use .Pq see Sx FORMAT SPECIFIERS . .It Xo .Ic relay .Op Ic backup Op Ar mx .Op Ic as Ar address .Op Ic source Ar source .Bk -words .Op Ic hostname Ar name .Op Ic hostnames Ar names .Ek .Op Ic pki Ar pkiname .Op Ic tls | verify .Xc Mail is relayed. The routing decision is based on the DNS system. .Pp If the .Ic backup parameter is specified, the current server will act as a backup server for the target domain. Accepted mails are only relayed through servers with a lower preference value in the MX record for the domain than the one specified in .Ar mx . If .Ar mx is not specified, the default server name will be assumed. .Pp If the .Ic as parameter is specified, .Xr smtpd 8 will rewrite the sender advertised in the SMTP session. .Ar address may be a user, a domain prefixed with .Sq @ , or an email address, causing smtpd to rewrite the user-part, the domain-part, or the entire address, respectively. .Pp If the .Ic source parameter is specified, .Xr smtpd 8 will explicitly bind to an address found in the table referenced by .Ar source when connecting to the relay. If the table contains more than one address, they are picked in turn each time a new connection is opened. .Pp By default, when connecting to a remote server, .Xr smtpd 8 advertises its default server name. A .Ic hostname parameter may be specified to advertise the alternate hostname .Ar name . If the .Ic source parameter is used, the .Ic hostnames parameter may be specified to advertise a hostname based on the source address. Table .Ar names contains a mapping of IP addresses to hostnames and .Xr smtpd 8 will automatically select the name that matches its source address when connected to the remote server. The .Ic hostname and .Ic hostnames parameters are mutually exclusive. .Pp When relaying, STARTTLS is always attempted if available on remote host and OpenSMTPD will try to present a certificate matching the outgoing hostname if one is registered in the pki. If .Ic pki is specified, the certificate registered for .Ar pkiname is used instead. .Pp If .Ic tls is specified, OpenSMTPD will refuse to relay unless the remote host provides STARTTLS. .Pp If .Ic verify is specified, OpenSMTPD will refuse to relay unless the remote host provides STARTTLS and the certificate it presented has been verified. .Pp Note that the .Ic tls and .Ic verify options are mutually exclusive and should only be used in private networks as they will prevent proper relaying on the Internet. .It Xo .Ic relay via .Ar host .Op Ic auth Aq Ar auth .Op Ic as Ar address .Op Ic source Ar source .Op Ic hostname Ar name .Op Ic hostnames Ar names .Op Ic pki Ar pkiname .Op Ic verify .Xc Mail is relayed through the specified .Ar host expressed as a URL. For example: .Bd -literal -offset indent smtp://mx1.example.org # use SMTP smtp://mx1.example.org:4321 # use SMTP \e # with port 4321 lmtp://localhost:2026 # use LMTP \e # with port 2026 .Ed .Pp The communication channel may be secured using one of the secure schemas. For example: .Bd -literal -offset indent tls://mx1.example.org # use TLS smtps://mx1.example.org # use SMTPS secure://mx1.example.org # try SMTPS and \e # fallback to TLS .Ed .Pp In addition, credentials for authenticated relaying may be provided when using a secure schema. For example: .Bd -literal -offset indent tls+auth://label@mx.example.org # over TLS smtps+auth://label@mx.example.org # over SMTPS secure+auth://label@mx.example.org # over either \e # SMTPS or TLS .Ed .Pp If a pki entry exists for the outgoing hostname, or one is provided with .Ar pkiname , the associated certificate will be sent to the remote server. .Pp If an SMTPAUTH session with .Ar host is desired, the .Ic auth parameter is used to specify the .Ar auth table that holds the credentials. Credentials will be looked up using the label provided in the URL. .Pp If the .Ic as parameter is specified, .Xr smtpd 8 will rewrite the sender advertised in the SMTP session. .Ar address may be a user, a domain prefixed with .Sq @ , or an email address, causing smtpd to rewrite the user-part, the domain-part, or the entire address, respectively. .Pp If the .Ic source parameter is specified, .Xr smtpd 8 will explicitly bind to an address found in the table referenced by .Ar table when connecting to the relay. If the table contains more than one address, they are picked in turn each time a new connection is opened. .Pp By default, when connecting to a remote server, .Xr smtpd 8 advertises its default server name. A .Ic hostname parameter may be specified to advertise the alternate hostname .Ar name . If the .Ic source parameter is used, the .Ic hostnames parameter may be specified to advertise a hostname based on the source address. Table .Ar names contains a mapping of IP addresses to hostnames and .Xr smtpd 8 will automatically select the name that matches its source address when connected to the remote server. The .Ic hostname and .Ic hostnames parameters are mutually exclusive. .El .Pp If .Ic verify is specified, OpenSMTPD will refuse to relay unless the remote host provides STARTTLS and the certificate it presented has been verified. The relay URL must specify TLS for this option to be valid. .Pp Additional per-rule adjustments available: .Bl -tag -width Ds .It Xo .Ic expire .Sm off .Ar n .Brq Cm s | m | h | d .Sm on .Xc Specify how long a message that matched this rule can stay in the queue. .El .It Xo .Ic bounce-warn .Sm off .Ar n .Brq Cm s | m | h | d .Oo , .Sm on .Ar ... .Oc .Xc Specify the delays for which temporary failure reports must be generated when messages are stuck in the queue. For example: .Bd -literal -offset indent bounce-warn 1h, 6h, 2d .Ed .Pp will generate a failure report when an envelope is in the queue for more than one hour, six hours and two days. The default is 4h. .It Xo .Ic expire .Sm off .Ar n .Brq Cm s | m | h | d .Sm on .Xc Specify how long a message can stay in the queue. The default value is 4 days. For example: .Bd -literal -offset indent expire 4d # expire after 4 days expire 10h # expire after 10 hours .Ed .It Xo .Ic limit mta .Op Ic for Ic domain Ar domain .Ar family .Xc Instruct .Xr smtpd 8 to only use the specified address .Ar family for outgoing connections. Accepted values are .Ic inet4 and .Ic inet6 . If a .Ar domain is specified, the restriction only applies when connecting to MXs for this domain. .It Xo .Ic limit scheduler max-inflight .Ar num .Xc Suspend the scheduling of envelopes for deliver/relay until the number of inflight envelopes falls below .Ar num . Changing the default value might degrade performances. .It Xo .Bk -words .Ic listen on Ar interface .Op Ar family .Op Ic port Ar port .Op Ic tls | tls-require | tls-require verify | smtps | secure .Op Ic pki Ar pkiname .Op Ic auth | auth-optional | auth Ar authtable | Ic auth-optional Ar authtable .Op Ic tag Ar tag .Op Ic hostname Ar hostname .Op Ic hostnames Ar names .Op Ic mask-source .Ek .Xc Specify an .Ar interface and .Ar port to listen on. An interface group, an IP address or a domain name may be used in place of .Ar interface . The .Ar family parameter can be used to listen only on specific address family. Accepted values are .Ic inet4 and .Ic inet6 . .Pp Secured connections are provided either using STARTTLS .Pq Ic tls , by default on port 25, or SMTPS .Pq Ic smtps , by default on port 465. .Ic tls-require may be used to force clients to establish a secure connection before being allowed to start an SMTP transaction. .Pp If .Ic tls-require verify is specified, the client must provide a valid certificate to be able to establish an SMTP session. .Pp .Ic secure may be specified to provide both STARTTLS and SMTPS services. Host certificates may be used for these connections, and must be priorly declared using the pki directive. If .Ic pki is specified, a certificate matching .Ic name is searched for. .Pp If the .Ic auth parameter is used, then a client may only start an SMTP transaction after a successful authentication. Any remote sender that passed SMTPAUTH is treated as if it was the server's local user that was sending the mail. This means that filter rules using "from local" will be matched. If .Ic auth-optional is specified, then SMTPAUTH is not required to establish an SMTP transaction. This is only useful to let a listener accept incoming mail from untrusted senders and outgoing mail from authenticated users in situations where it is not possible to listen on the submission port. .Pp Both .Ic auth and .Ic auth-optional accept a table as parameter. When provided, credentials are looked up in this table. Credentials format is described in .Xr table 5 . .Pp If the .Ic tag parameter is used, then clients connecting to the listener will be tagged .Ar tag . .Pp If the .Ic hostname parameter is used, then it will be used in the greeting banner instead of the default server name. .Pp The .Ic hostnames parameter overrides the server name for specific addresses. Table .Ar names contains a mapping of IP addresses to hostnames and .Xr smtpd 8 will use the hostname that matches the address on which the connection arrives if it is found in the mapping. .Pp If the .Ic mask-source parameter is used, then the listener will skip the "from" part when prepending the "Received" header. .It Ic max-message-size Ar n Specify a maximum message size of .Ar n bytes. The argument may contain a multiplier, as documented in .Xr scan_scaled 3 . The default maximum message size is 35MB if none is specified. .It Ic pki Ar hostname Ic certificate Ar certfile Associate the certificate located in .Ar certfile with .Ar hostname . .Pp A certificate chain may be created by appending one or many certificates, including a Certificate Authority certificate, to .Ar certfile . .Pp Creation of certificates is documented in .Xr starttls 8 . .It Ic pki Ar hostname Ic key Ar keyfile Associate the key located in .Ar keyfile with .Ar hostname . .It Ic pki Ar hostname Ic ca Ar cafile Associate a custom CA certificate .Ar cafile with .Ar hostname . .It Ic pki Ar hostname Ic dhparams Ar dhfile Associate the Diffie-Hellman parameters located in .Ar dhfile with .Ar hostname . .Pp The parameters are used for ephemeral key exchange. If not specified, OpenSMTPD will use safely generated builtin parameters. .Pp Creation of Diffie-Hellman parameters is documented in .Xr openssl 1 . .It Ic queue compression Enable transparent compression of envelopes and messages. The only supported algorithm at the moment is gzip. Envelopes and messages may be inspected using the .Xr smtpctl 8 or .Xr gzcat 1 utilities. .It Ic queue encryption Op key Ar key Enable transparent encryption of envelopes and messages. .Ar key must be a 16-byte random key in hexadecimal representation. It can be obtained using the .Xr openssl 1 utility as follow: .Bd -literal -offset indent $ openssl rand \-hex 16 .Ed .Pp If the .Ar key parameter is not specified, it is read with .Xr getpass 3 at startup. If .Ar key is "stdin", then it is read from the standard input at startup. .Pp The only supported algorithm is AES-256 in GCM mode. Envelopes and messages may be inspected using the .Xr smtpctl 8 utility. .Pp Queue encryption can be used with queue compression and will always perform compression before encryption. .It Ic table Ar name Oo Ar type : Oc Ns Ar config Tables are used to provide additional configuration information for .Xr smtpd 8 in the form of lists or key-value mappings. The format of the entries depends on what the table is used for. Refer to .Xr table 5 for the exhaustive documentation. .Pp The table is identified using table name .Ar name ; the name itself is arbitrarily chosen. .Pp .Ar type specifies the table backend, and should be one of the following: .Pp .Bl -tag -width "fileXXX" -compact .It db Information is stored in a file created using .Xr makemap 8 . .It file Information is stored in a plain text file using the same format as used to generate .Xr makemap 8 mappings. This is the default. .El .Pp .Ar config specifies a configuration file for the table data. It must be an absolute path to a file for the .Dq file and .Dq db table types. .It Ic table Ar name Brq Ar value Op , Ar ... Tables containing list of static values may be declared using an inlined notation. .Pp The table is identified using table name .Ar name ; the name itself is arbitrarily chosen. .Pp The table must contain at least one value and may declare many values as a list of comma separated strings. .It Ic table Ar name Brq Ar key Ns = Ns Ar value Op , Ar ... Tables containing static key-value mappings may be declared using an inlined notation. .Pp The table is identified using table name .Ar name ; the name itself is arbitrarily chosen. .Pp The table must contain at least one key-value mapping and may declare many mappings as a list of comma separated .Ar key Ns = Ns Ar value descriptions. .El .Ss FORMAT SPECIFIERS Some configuration directives support expansion of their parameters at runtime. Such directives (for example .Ar deliver to maildir , .Ar deliver to mda ) may use format specifiers which will be expanded before delivery or relaying. The following formats are currently supported: .Bd -literal -offset indent %{sender} sender email address %{sender.user} user part of the sender email address %{sender.domain} domain part of the sender email address %{rcpt} recipient email address %{rcpt.user} user part of the recipient email address %{rcpt.domain} domain part of the recipient email address %{dest} recipient email address after expansion %{dest.user} user part after expansion %{dest.domain} domain part after expansion %{user.username} local user %{user.directory} home directory of the local user .Ed .Pp Expansion formats also support partial expansion using the optional bracket notations with substring offset. For example, with recipient domain "example.org": .Bd -literal -offset indent %{rcpt.domain[0]} expands to "e" %{rcpt.domain[1]} expands to "x" %{rcpt.domain[8:]} expands to "org" %{rcpt.domain[-3:]} expands to "org" %{rcpt.domain[0:6]} expands to "example" %{rcpt.domain[0:-4]} expands to "example" .Ed .Pp In addition, modifiers may be applied to the token. For example, with recipient "User+Tag@Example.org": .Bd -literal -offset indent %{rcpt:lowercase} expands to "user+tag@example.org" %{rcpt:uppercase} expands to "USER+TAG@EXAMPLE.ORG" %{rcpt:strip} expands to "User@Example.org" %{rcpt:lowercase|strip} expands to "user@example.org" .Ed .Pp For security concerns, expanded values are sanitized and potentially dangerous characters are replaced with ":". In situations where they are desirable, the "raw" modifier may be applied. For example, with recipient "user+t?g@example.org": .Bd -literal -offset indent %{rcpt} expands to "user+t:g@example.org" %{rcpt:raw} expands to "user+t?g@example.org" .Ed .Sh FILES .Bl -tag -width "/etc/mail/smtpd.confXXX" .It Pa /etc/mail/smtpd.conf Default .Xr smtpd 8 configuration file. .It Pa /etc/mail/mailname If this file exists, the first line is used as the server name. Otherwise, the server name is derived from the local hostname returned by .Xr gethostname 3 , either directly if it is a fully qualified domain name, or by retreiving the associated canonical name through .Xr getaddrinfo 3 . .It Pa /var/spool/smtpd/ Spool directories for mail during processing. .El .Sh EXAMPLES The default .Nm file listens on the loopback network interface (lo0), and allows for mail from users and daemons on the local machine, as well as permitting email to remote servers. Some more complex configurations are given below. .Pp This first example is the same as the default configuration, but all outgoing mail is forwarded to a remote SMTP server. A secrets file is needed to specify a username and password: .Bd -literal -offset indent # touch /etc/mail/secrets # chmod 640 /etc/mail/secrets # chown root:_smtpd /etc/mail/secrets # echo "label username:password" > /etc/mail/secrets # makemap /etc/mail/secrets .Ed .Pp .Nm would look like this: .Bd -literal -offset indent listen on lo0 table aliases db:/etc/mail/aliases.db table secrets db:/etc/mail/secrets.db accept for local alias deliver to mbox accept for any relay via tls+auth://label@smtp.example.com \e auth .Ed .Pp In this second example, the aim is to permit mail relaying for any user that can authenticate using their normal login credentials. An RSA certificate must be provided to prove the server's identity. The mail server listens on all interfaces the default route(s) point to. Mail with a local destination should be sent to an external mda. First, the RSA certificate is created: .Bd -literal -offset indent # openssl genrsa \-out /etc/ssl/private/mail.example.com.key 4096 # openssl req \-new \-x509 \-key /etc/ssl/private/mail.example.com.key \e \-out /etc/ssl/mail.example.com.crt \-days 365 # chmod 600 /etc/ssl/mail.example.com.crt # chmod 600 /etc/ssl/private/mail.example.com.key .Ed .Pp In the example above, a certificate valid for one year was created. The configuration file would look like this: .Bd -literal -offset indent pki mail.example.com certificate "/etc/ssl/mail.example.com.crt" pki mail.example.com key "/etc/ssl/private/mail.example.com.key" listen on lo0 listen on egress tls pki mail.example.com auth table aliases db:/etc/mail/aliases.db accept for local alias deliver to mda "/path/to/mda \-f \-" accept from any for domain example.org \e deliver to mda "/path/to/mda \-f \-" accept for any relay .Ed .Sh SEE ALSO .Xr mailer.conf 5 , .Xr table 5 , .Xr makemap 8 , .Xr smtpd 8 .Sh HISTORY .Xr smtpd 8 first appeared in .Ox 4.6 . opensmtpd-5.4.2p1/smtpd/smtpd.h010064400017500000000000001041401230543430200156100ustar00gilleswheel/* $OpenBSD$ */ /* * Copyright (c) 2008 Gilles Chehade * Copyright (c) 2008 Pierre-Yves Ritschard * Copyright (c) 2012 Eric Faurot * * Permission to use, copy, modify, and distribute this software for any * purpose with or without fee is hereby granted, provided that the above * copyright notice and this permission notice appear in all copies. * * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF * MERCHANTABILITY AND FITNESS.

A list consists of a series of values, while a mapping consists of a series of keys and their associated values. The following illustrates how to declare them as static tables: .Bd -literal -offset indent table mylist { value1, value2, value3 } table mymapping { key1 = value1, key2 = value2, key3 = value3 } .Ed .Pp When using a .Ql file table, a list will be written with each value on a line by itself: .Bd -literal -offset indent value1 value2 value3 .Ed .Pp A mapping will be written with each key and value on a line, whitespaces separating both columns: .Bd -literal -offset indent key1 value1 key2 value2 key3 value3 .Ed .Pp A file table can be converted to a .Xr db 3 database using the .Xr makemap 8 utility with no syntax change. .Pp Tables using a .Ql file or .Xr db 3 backend will be referenced as follows: .Bd -literal -offset indent table name file:/path/to/file table name db:/path/to/file.db .Ed .Ss Aliasing tables Aliasing tables are mappings that associate a recipient to one or many destinations. They can be used in two contexts: primary domain aliases and virtual domain mapping. .Bd -literal -offset indent accept for domain example.org alias deliver to mbox accept for domain example.org virtual deliver to mbox .Ed .Pp In a primary domain context, the key is the user part of the recipient address, whilst the value is one or many recipients as described in .Xr aliases 5 : .Bd -literal -offset indent user1 otheruser user2 otheruser1,otheruser2 user3 otheruser@example.com .Ed .Pp In a virtual domain context, the key is either a user part, a full email address or a catch all, following selection rules described in .Xr smtpd.conf 5 , and the value is one or many recipients as described in .Xr aliases 5 : .Bd -literal -offset indent user1 otheruser user2@example.org otheruser1,otheruser2 @example.org otheruser@example.com @ catchall@example.com .Ed .Ss Domain tables Domain tables are simple lists of domains. They can only be used in one context: .Bd -literal -offset indent accept for domain deliver to mbox .Ed .Pp In that context, the list of domains will be matched against the recipient domain. For .Ql static , .Ql file and .Xr db 3 backends, a wildcard may be used so the domain table may contain: .Bd -literal -offset indent example.org *.example.org .Ed .Ss Credentials tables Credentials tables are mappings of credentials. They can be used in two contexts: .Bd -literal -offset indent listen on tls [...] auth accept for any relay tls+auth://label@host auth .Ed .Pp In a listener context, the credentials are a mapping of username and encrypted passwords: .Bd -literal -offset indent user1 $2a$06$hIJ4QfMcp.90nJwKqGbKM.MybArjHOTpEtoTV.DgLYAiThuoYmTSe user2 $2a$06$bwSmUOBGcZGamIfRuXGTvuTo3VLbPG9k5yeKNMBtULBhksV5KdGsK .Ed .Pp The passwords are to be encrypted using the .Xr smtpctl 8 encrypt subcommand. .Pp In a relay context, the credentials are a mapping of labels and username:password pairs, where the username may be omitted if identical to the label: .Bd -literal -offset indent label1 user:password label2 password .Ed .Pp The label must be unique and is used as a selector for the proper credentials when multiple credentials are valid for a single destination. The password is not encrypted as it must be provided to the remote host. .Ss Netaddr tables Netaddr tables are lists of IPv4 and IPv6 network addresses. They can only be used in the following context: .Bd -literal -offset indent accept from source for domain example.org deliver to mbox .Ed .Pp When used as a "from source", the address of a client is compared to the list of addresses in the table until a match is found. .Pp A netaddr table can contain exact addresses or netmasks, and looks as follow: .Bd -literal -offset indent 192.168.1.1 ::1 ipv6:::1 192.168.1.0/24 .Ed .Ss Userinfo tables User info tables are used to described virtual system users. They are used in rule context to specify an alternate user base, mapping virtual users to local system UID, GID and home directory. .Bd -literal -offset indent accept for domain example.org userbase deliver to maildir .Ed .Pp The userinfo table is a mapping from virtual user names to a set of system user ID, group ID and path to home directory. .Pp A userinfo table looks as follows: .Bd -literal -offset indent joe 1000:100:/home/virtual/joe jack 1000:100:/home/virtual/jack .Ed .Pp In this example, both joe and jack are virtual users mapped to the local system user with UID 1000 and GID 100, but different home directories. These directories may contain a .Xr forward 5 file. .Ss Source tables Source tables are lists of IPv4 and IPv6 addresses. They can only be used in the following context: .Bd -literal -offset indent accept for domain example.org relay source .Ed .Pp Successive queries to the source table will return the elements one by one. .Pp A source table looks as follow: .Bd -literal -offset indent 192.168.1.2 192.168.1.3 ::1 ::2 ipv6:::3 ipv6:::4 .Ed .Ss Mailaddr tables Mailaddr tables are lists of email addresses. They can be used in the following contexts: .Bd -literal -offset indent accept sender for domain example.org deliver to mbox accept for domain example.org recipient deliver to mbox .Ed .Pp A mailaddr entry is used to match an email address against a username, a domain or a full email address. A "*" wildcard may be used in part of the domain name. .Pp A mailaddr table looks as follow: .Bd -literal -offset indent user @domain user@domain user@*.domain .Ed .Ss Addrname tables Addrname tables are used to map IP addresses to hostnames. They can be used in both listen context and relay context: .Bd -literal -offset indent listen on 0.0.0.0 hostnames accept for any relay hostnames .Ed .Pp In listen context, the table is used to look up the server name to advertise depending on the local address of the socket on which a connection is accepted. In relay context, the table is used to determine the hostname for the HELO sequence of the SMTP protocol, depending on the local address used for the outgoing connection. .Pp The format is a mapping from inet4 or inet6 addresses to hostnames: .Bd -literal -offset indent ::1 localhost 127.0.0.1 localhost 88.190.23.165 www.opensmtpd.org .Ed .Sh SEE ALSO .Xr smtpd.conf 5 , .Xr makemap 8 , .Xr smtpd 8 opensmtpd-5.4.2p1/smtpd/table.c010064400017500000000000000412041230532062500155460ustar00gilleswheel/* $OpenBSD$ */ /* * Copyright (c) 2013 Eric Faurot * Copyright (c) 2008 Gilles Chehade * * Permission to use, copy, modify, and distribute this software for any * purpose with or without fee is hereby granted, provided that the above * copyright notice and this permission notice appear in all copies. * * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF * MERCHANTABILITY AND FITNESS.

The information is encoded using the traditional .Xr passwd 5 format and allows the sharing of a user database across different software supporting this format. .Pp The table is used by .Xr smtpd 8 when authenticating a user or when user information such as user-id or home directory is required for a delivery. .Pp A "passwd" table consists of a flat file containing the user entries, each one on a line by itself, with fields separated by a colon: .Bd -literal -offset indent gilles:*:1000:1000:Gilles:/home/gilles:/sbin/nologin eric:*:1001:1001:Eric:/home/eric:/sbin/nologin chl:*:1002:1002:Charles:/home/chl:/sbin/nologin .Ed .Pp If the table is used for authentication, the second field may contain a password encrypted using the .Xr crypt 3 function. Such passwords can be generated using the .Xr encrypt 1 utility or .Xr smtpctl 8 encrypt command. .Sh SEE ALSO .Xr passwd 5 , .Xr smtpd.conf 5 , .Xr smtpctl 8 , .Xr smtpd 8 opensmtpd-5.4.2p1/smtpd/table_passwd.c010064400017500000000000000121511230532062500171260ustar00gilleswheel/* $OpenBSD$ */ /* * Copyright (c) 2013 Gilles Chehade * * Permission to use, copy, modify, and distribute this software for any * purpose with or without fee is hereby granted, provided that the above * copyright notice and this permission notice appear in all copies. * * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF * MERCHANTABILITY AND FITNESS.

In other projects, it is set to # '$srcdir', '$srcdir/..', or '$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is '.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.
